The VMA awards are tonight and one of the viral stories you’re sure to hear about tomorrow is an altercation between MMA fighter Conor McGregor and singer Machine Gun Kelly who arrived at the awards show with Megan Fox who wore this see-through dress:

Nobody seems to know exactly why McGregor and Kelly got into it, however:

Watch for yourself:

The New York Post reported that the fight may have started after McGregor threw a drink on Kelly:

Our source added that McGregor allegedly threw his drink at Kelly and then the fight broke out.

“They scuffled then it settled down and Connor went for him again,” the source said, adding, that the photographers “weren’t happy” and were “saying they were going to boycott Connor because they were worried MGK and Megan wouldn’t walk.”

It wasn’t immediately clear what the squabble was over but McGregor’s rep denied that the fight occurred despite the photo evidence.

“Conor only fights fighters,” his rep told Page Six in a statement.
